Highlights

THE electronic toll collection (ETC) system utilizing dedicated short-range communication (DSRC) at 5.8 GHz has drawn extensive attention during the past decade
To effectively trade-off the power consumption and sensitivity, we propose a PLL-less receiver architecture, which is fabricated in a 0.18μm CMOS process
The typical power consumed by an IEEE 802.15.4 transceiver implemented in a 0.18μm CMOS process is in the range of 18 mW to 32 mW while the transceiver is operated in its receive mode [9,10,11,12,13]

Summary

Introduction

THE electronic toll collection (ETC) system utilizing dedicated short-range communication (DSRC) at 5.8 GHz has drawn extensive attention during the past decade. The RSU and the OBU are installed at the toll station and the vehicle, respectively. Both the Japanese/Korean and Chinese standards support amplitude shift key (ASK) modulation, but the required data rates are different. Since the system designed for the Japanese/Korean standard is powered by the vehicle, the primary aim is to achieve a high data rate, such as 1024 kbps and 4096 kbps with sensitivity of -60 dBm, depending on whether ASK or QPSK modulation is utilized.
